Exhibit 99.1 Catalyst Semiconductor Reports 4th Quarter and Fiscal Year Results SUNNYVALE, Calif.--(BUSINESS WIRE)--July 20, 2006--Catalyst Semiconductor, Inc. (NASDAQ:CATS), a developer and marketer of programmable and analog/mixed signal products used in telecommunications, networking systems, computation, automotive, industrial and consumer markets, today announced financial results for its fiscal fourth quarter and year ended April 30, 2006. For the quarter ended April 30, 2006, Catalyst reported net income of $270,000, or $0.02 per diluted share, on net revenue of $14.2 million. This compares with net income of $516,000, or $0.03 per diluted share, on net revenue of $16.3 million in the quarter ended April 30, 2005. In the quarter ended January 31, 2006, Catalyst reported net income of $864,000, or $0.05 per diluted share, on net revenue of $14.4 million. For the year ended April 30, 2006, Catalyst reported net income of $2.6 million, or $0.14 per diluted share, on revenue of $60.2 million. This compares to net income of $3.8 million, or $0.20 per diluted share, in the previous year on revenue of $62.3 million. Net revenue from analog/mixed signal products totaled $1,164,000, or 8.2% of revenue, in the quarter ended April 30, 2006, compared with $901,000, or 5.5% of revenue, in the quarter ended April 30, 2005 and $1,123,000, or 7.8% of net revenue, in the quarter ended January 31, 2006. Gross margin for the quarter ended April 30, 2006 was 34.9%, compared to 37.9% for the quarter ended April 30, 2005 and 43.1% for the quarter ended January 31, 2006. Several factors impacted the fourth quarter margin compared to the previous quarter including a net increase in reserve for excess inventory of $89,000, increased overhead expenses of $146,000, as well as increased costs to manufacture certain parts. In the quarter ended January 31, 2006, Catalyst recorded a benefit from the sale of previously reserved inventory of $280,000. Gross margin for the year ended April 30, 2006 was 38.7% compared to 42.5% in the year ended April 30, 2005. The decrease was due primarily to the challenging pricing environment, particularly in the serial memory line which represented approximately 58% of fiscal 2006 revenue. Catalyst continues to pursue product cost reduction programs including transition to .35 micron products. Research & Development expenses decreased $112,000, or 5.9%, to $1.8 million for the quarter ended April 30, 2006 from $1.9 million for the quarter ended April 30, 2005 and $108,000, or 5.7%, from $1.9 million for the quarter ended January 31, 2006. The decrease from the prior year was due primarily to a decrease in costs for professional services of $51,000 and a decrease of $45,000 in spending for engineering equipment. The decrease from the previous quarter was due primarily to a $114,000 reduction in employee compensation related expenses. Sales, General & Administrative expenses decreased $337,000, or 8.9%, to $3.4 million in the quarter ended April 30, 2006 from $3.8 million in the quarter ended April 30, 2005 and increased $163,000, or 5.0%, from $3.3 million in the quarter ended January 31, 2006. These periodic fluctuations resulted partially from the level and timing of costs attributable to Sarbanes-Oxley related expenses. Catalyst recorded an income tax benefit of $216,000 during the quarter ended April 30, 2006 compared to income tax provisions of $218,000, or a tax rate of 29.7%, in the quarter ended April 30, 2005 and $539,000, or 38.4%, in the quarter ended January 31, 2006. The tax benefit recorded for the quarter ended April 30, 2006 was attributable to expiry of the statute of limitation and resulted in an effective tax rate of 28.5% for fiscal 2006. The tax rate in the quarter ended April 30, 2006 benefited by $284,000 from a reduction in state tax liability. As of April 30, 2006, Catalyst had cash, cash equivalents and short-term investments of $29.1 million, a decrease of $3.8 million compared to January 31, 2006. The decrease in cash was primarily attributable to the purchase of a building for $3.7 million to serve as Catalyst's future headquarters facility and stock repurchases of 388,184 shares at a cost of $1,920,000, or an average cost of $4.95 per share. During fiscal 2006, Catalyst repurchased 912,943 shares at a total cost of $4,503,000, or $4.93 per share. The company had previously provided a preliminary estimate of fourth quarter revenues but reporting of final results had been delayed by complications encountered in the recent implementation of a more sophisticated inventory tracking and cost accounting system. The system significantly improved our ability to track and monitor inventory quantities, but its implementation resulted in unanticipated delays in closing our books and completing our assessment of the effectiveness of the company's internal control over financial reporting as required by the Sarbanes-Oxley Act under Section 404. Management Comments & Outlook "While we are pleased to record our 8th consecutive fiscal year of profitability, we are nevertheless concerned about the continuing pricing pressure on our serial EEPROM product line. We continue to focus our attention on cost reduction programs for this particular product line and the volume from our new process platform is picking up. "Despite fluctuations on a quarter to quarter basis, we are encouraged by the revenue increase achieved for our line of analog/mixed signal products, which totaled $4.6 million in revenues for fiscal 2006 compared to $2.9 million for fiscal 2005. We are increasing the pace of new product introductions, coupled with increasing marketing efforts and design wins, to accelerate our rate of success in the coming quarters," said Gelu Voicu, president and chief executive officer.
